The aforementioned “plants” include plants, to which tolerance to HPPD inhibitors such as isoxaflutole, ALS inhibitors such as imazethapyr and thifensulfuron-methyl, EPSP synthetase inhibitors such as glyphosate, glutamine synthetase, inhibitors such as glufosinate, acetyl-CoA carboxylase inhibitors such as sethoxydim, and herbicides such as bromoxynil, dicamba and 2,4-D has been conferred by a classical breeding method or by genetic engineering techniques.

Examples of a “plant” on which tolerance has been conferred by a classical breeding method include rape, wheat, sunflower and rice tolerant to imidazolinone ALS inhibitory herbicides such as imazethapyr, which are already commercially available under a product name of Clearfield (registered trademark). Similarly, there is a soybean on which tolerance to sulfonylurea ALS inhibitory herbicides such as thifensulfuron-methyl has been conferred by a classical breeding method, which is already commercially available under a product name of STS soybean.

Examples of a plant on which tolerance to acetyl-CoA carboxylase inhibitors such as trione oxime or aryloxy phenoxypropionic acid herbicides has been conferred by a classical breeding method include SR corn. The plant on which tolerance to acetyl-CoA carboxylase inhibitors has been conferred is described in Proceedings of the National Academy of Sciences of the United States of America (Proc. Natl. Acad. Sci. USA), vol. 87, pp. 7175-7179 (1990). A variation of acetyl-CoA carboxylase tolerant to an acetyl-CoA carboxylase inhibitor is reported in Weed Science, vol. 53, pp. 728-746 (2005) and a plant tolerant to acetyl-CoA carboxylase inhibitors can be generated by introducing a gene of such an acetyl-CoA carboxylase variation into a plant by genetically engineering technology, or by introducing a variation conferring tolerance into a plant acetyl-CoA carboxylase.

Plants tolerant to acetyl-CoA carboxylase inhibitors or ALS inhibitors or the like can be generated by introducing into the plant cell a nucleic acid for introduction of base-substitution variation represented by Chimeraplasty Technique (Gura T. 1999. Repairing the Genome's Spelling Mistakes. Science 285: 316-318) to introduce a site-directed amino acid substitution variation into an acetyl-CoA carboxylase gene or an ALS gene of the plant.

Examples of a plant on which tolerance has been conferred by genetic engineering technology include corn, soybean, cotton, rape and sugar beet which are tolerant to glyphosate, and which have been commercially available under a product name of RoundupReady (registered trademark), AgrisureGT, and so on.
